astronomer usingJames Webb Space Telescope(JWST ) datum have see a monolithic range of mountains of at least 20 closely packed galaxies from the early universe , and it could reveal insight into how the most massive structures in the cosmos form .
This megastructure — nicknamed the " Cosmic Vine " in a study published Nov. 8 to the preprint databasearXiv — swoops through quad in a curtain call shape , estimated to extend more than 13 million sluttish - years long and about 650,000 light - years widely . ( For comparison , ourMilky Waygalaxy is about 100,000 light - years wide . ) Astronomers detected the Brobdingnagian tendril of petrol and galaxies while study JWST observations of an area called the Extended Groth Strip , site between the configuration Ursa Major and Boötes .

The team was calculate specifically for Light Within from very other coltsfoot , focusing on a place call red shift , a bar of how light growth in wavelength as it travels immense distances through theexpanding universe . All of the galaxies notice in the Cosmic Vine showed a redshift of rough 3.44 , entail the light emitted by the objects journey between 11 billion and 12 billion years — or for most of our 13.8 billion - year - old macrocosm ’s life — before reach JWST ’s lens .

The Cosmic Vine is " importantly larger " than other galaxy groups abide by so early in the universe ’s chronicle , the team spell , add it to a growing inclination ofsurprisingly huge structure in the early universediscovered by JWST . According to the researchers , the Vine is likely on its way to becoming a beetleweed clump ; these are the most massive construction in the population recoil together by gravity , with masse typically ranging from hundreds of 1000000000000 to quadrillions of prison term the mass of Earth ’s Dominicus .
For now , the Cosmic Vine has an estimated wad of about 260 billion solar masses and is still growing — but its two large galaxies may be quick to call it quits . While take the wavelengths of light emitted by the two galaxy , the researchers ground that hotshot formation has all but stopped there , fate them as " quiescent " or " quench " galaxy .

The authors reflect , what is " the culprit quenching ace organization " at such an former cosmic time ? They noted that it is strange to find such tumid galaxies already running blue on asterisk - forming gas in the ancient creation . One possibility is that both galaxies are the results of recent galactic merger , withcosmic collisionstriggering wild bursts of star formation that depleted most of the galaxies ' useable gaseous state about half a billion years before JWST ’s observations , the researchers wrote .
As with many recent JWST discoveries , the Cosmic Vine raise more questions about the nature of our cosmos than it answers , and further study is needed to lick the mystery lock behind this ancient astronomic concatenation .
